Abstract
An implementation scheme of the adaptive fiber-optic laser hydrophone with a membrane-type fiber-optic sensor as a sensitive element is proposed and studied. The sensor signal is phase demodulated using an adaptive holographic interferometer whose key element is a dynamic hologram formed in a photorefractive CdTe crystal. The hydrophone is distinguished by high noise immunity and high sensitivity (–117 dB rel. to 1 V/µPa at a frequency of 4.9 kHz) providing stable detection of hydroacoustic signals with an acoustic pressure from 31 dB (rel. to 20 µPa) in the dynamic range to 42 dB (at 9.6 kHz).
